Abstract
A bending machine for elongated workpieces, comprising a bending tool with a bending head having a bending disc with a bending groove and two slide rails, each having a molding groove and which can be placed laterally against opposing sides of the workpiece. Each slide rail is secured to a support part and laterally supports the workpiece from where the workpiece is fed into the bending groove to a point in front of the bending groove when the slide rail is resting against the workpiece. Each support part is adjustable between a starting position, in which the slide rail does not rest against the workpiece, and a final position, in which the slide rail contacts the workpiece. Upon contacting the workpiece, the other slide rail assumes its starting position. The support parts are attached to a two-arm lever, and a slide piece rests against the workpiece in each lever position.
